Dear Robert, I had a similar issue with the 2015 Macbook Pro and there's a workaround: you need to wait A LOT, like 2+ hours for it to get through the "being stuck at sd0" phase, then install, wait out the similarly long first boot, and then recompile the kernel with a patched acpi.c. Patch is available here:
https://openbsdonapple.wiki/doku.php?id=misc:acpi_patch Could you please send me a message off-list with yuor dmesg and whether the above patch worked so I can collate in that above wiki?
